I absolutely love these things!! They actually work. When I get home from the grocery store, I wash the fruit or veggies immediately and put into these containers. I like to label them because then it is obviously easier to find what you are looking for. I used dry erase pens for these, posts-its work or maybe you can use a sharpie for things you always have. We are never without cucumbers so I could probably make a permanent one for that. Write the date on if you want, draw little pictures for the kiddos so they can learn their words, Tupperware Fun, who knew? Anyway, love these things, they stack great in the fridge and viola…fresh fruit and veggies that last longer.
